Tlie blades are mounted uponva rivet -12 which serves the additional vfunction of a` plates are*y transversely at 13. The handlemembers 11 are correspondingly slotted at 14, thisl arrangement resultingiin the openingat the end of thel device opposite to the blades, into'which a-check may be inserted for `thepurpose of receiving an impression` from a pair vof situated in said opening.

The confronting surfaces ofltheseI plates varefsuitably'roughened as a't f17,f-tlie4 particular design Vor style of roughening being immaterial. l

A lever 18 has connections 19. with one of the impression plates, the plate selected for .illustration being the upper oneVv 15' ac- Y y The connections consist of a pair of links which are .pivo'ted at 20`toone extremity of the lever 18, and at, v21 to a lug 22on theplatel. ,TheI lever the .connections y19,the long end of the lever entending,slightlyv beyond thefendv ofthe @.deviceas at 24fso thatithe user can readily take hold of theleverfand raiseit sulficiently .to move the impressionvplates together. y

rIhe latter end of the lever rests upon the rivet 12 which thus acts .as a-'stop to limit -tlie closing movement 'otthelever and the opening movement ofthe impression plates. Pins 25 serve the double pu-rposejolas-l rsisting in securingthe'bottoin plate 16, in

position and o :t gui'ding'the upper., plate 15 in vits movements in .respect .to the bottom plate. The bottom kplate is `additionally secured by asc'rew or other similar means 26, thereby holdingthe bottom'l plate' perfectpass through porytionsof the vback s'pringsS and 9 ,-(Figs. 2

and 4) and throughvbrace members 27 and 2.8 forming parts of the back springs.

These brace members are formed ,sub-

stantially as "shown in Figures 2 and ll.

Theyare `turned upwardly y andtoward the v adjacent end fof the device, as sliowmservving'as additional spacers between the partiH member/send" the back,y springsg'are 'addition- 15.115 riveted. 21h29 and 30, the Whol 21rrangement insnr-ing a l rigidv onstrnctionV especially inthe region of the transverse .open- CII ing. It is noted that the. lever 18 is sit-y uated between the partit-ion plates 5 and 6. A close lit is desirable in order that the lever may be frictionally held in the closed position. places adjacent to the fulcruin f'inorder `to make room for the connecting links 19.

A washer or collar 32 (Fig. Blinoun'ted on the rivet 29 between the. central pair of plates 5 and 6 insures the spacing between.

these plates and guards against any bind- /ing of the partition plates against the le-V verand thel connecting links 19.

The-operation is readily understood: The' owner or user of the device, desiring .to protect a'check which hephas written, will `insert the paper in the opening at one end formed by the various slots 13 and 14 and "between the impression plates 15 and 16,

whereupon he takes hold of the slight eX- tension 24e-(Fig. 3) and moves the lever 1S upon its fulcrum 23 to an opening position. This act serves to move the impression plate 15 toward the stationary impression plate 16, the former being connected with the latter by the links 19.

It is noted that the fulcrum 28 is relatively close to the point of connection with the npper'impression plate 15 and that the remainder of the lever at the other side of the fulcrum is relatively long. -A relatively light pressure against the point 24 will thus produce considerable pressure on the plate 15 against the paper so that the,y

rougliened surfaces 17 are readily impressed;

i The construction of ther device is such thaty -the user has all the advantages of an ordil nary pocket knife as well as 'those ofthe check protector, the function of one preventing no the other.

Vhile the construction and arrangement interference to the function of rvof the improved check protector is that of a generally preferred form,robviously modifications and c lianges may be made without departing from the spirit of the invention or the scope of the claims.

1. A pocket knife having blades and back springs to hold them in position; in combination, a pair. of impression plates, means carried by the back springs rigidly holding one of the plates Aand guiding the other plate, and a movablelever having connection with said other plate for moving it in respect to the rigidly held plate.
